I tried various servers, from EU countries to NA and Asia and speed was generally very good, between 50-60 Mbps which is more than enough for comfortable 4k HDR streaming/torrenting.
What is your normal internet speed without using any VPN?
50-60 Mbps is not bad but it could be better especially if your normal speed is much higher than that, but it all depends from country you choose, latency, percentage of use for specific location and other factors.
The search goes on. Or I will just use 2 different VPNs from now on, Mullvad + something else.
I saw that windscribe is offering location that are specialized servers used for streaming and netflix, there are four of them in Canada, United States, United Kingdom and Japan.
Only thing is that you can use this locations only with pro account I think, but I can't confirm that because I never tried if it works.
I wanted to try Surfshark that looks decent and they son't have any bandwidth limits or restrictions.
